The act of selecting. andpressinggakey conditions certain of 'thezcodingcircuits for: action during the. operating cycle,.each keyjcontrolling a differentv come 2,334,365: bination' of circuits so that the electrical impulses produced --co'mprise "wave trains: mechanically coded bythe action'of'the timer; -'Ihese'wave trains each includean initial or starting impulse which, when applied onthereceiver by means of astarting circuit', starts a timer switch in operation at a speed which is thesar'ne or approximately the same as that of the timer switch at the transmitter; The timer switch 'atthe receiver, in conjunction with a plurality of coding circuits, applies the coded train of impulses to relays which operate a mechanical selector and cause the character corresponding to the coded train to be printed; s It will be understood, of course, that the invention is not necessarily limited to any particular means for transmitting the coded electrical effects, but that any suitable expedient, including wired'or wireless transmission'means, may be employed for transmitting the electrical effects be-' tween the sending and receiving stations; and

while it is, of course, not essential that the equipmentat: the sendingand receiving stations be identical, for manufacturing convenience as well as'for convenienceof operation, I preferjto provide combined transmitter-receiver equipment at each station adapted not only to send but also to receive typewritten messages, to the'en'd that messages may be sent ineither direction from-either station. It is thought that the-advantage oi'thus providing combined transmitter-receiver mechanism will be obvious, since the major portion of the apparatusincluding the starting-and coding circuits and the timer switch; which are active when the device is in use asa transmitterjmay also lee-utilized when-the device isifunctioning as a receiver. The simplification andavoidance of duplication of parts accomplished by constructing the apparatus 'as' a combined transmitterreceiver will be readily apparent as the invention is more fully understood, although it is obvious that the equipment may be built for sending or for receiving purposes only.

THE ELECTRICAL SYSTEM The diagram of connections, Figure 15 illustrates a pair of sender-receiver devices, one of connected with 'selector switch means A, comprising a. turnable'member I5, and a plurality of contacts-connected with said circuits J and .F, and operable to condition the device as'a receiver by connecting the circuits FandJ with the power source directly, and alternately 'to condition the device for sending by placing the circuits under control of thekeyboard K.- i

The transmitter The coding circuits, atthe sending station, are associated with selectivelyoperable circuit conditioning means controlled by the typewriter keyboard K. This keyboard comprisesmanually de-, pressible keys l7, each ofwhich, when depressed, conditions a corresponding combination of circuits J for activity. duringthe sending cycle, others of the; circuits J remaining inactive." Each I of the, keys controls a different combination 7 for activity in various combinations. by means of which is shown in sending and the other in "re- 7 ceivin'g, position. These devices each comprise a timer switch forming coding means Z at each of the sending and receiving stations, thesaid timer switch preferably comprising a rotaryicir: cuit controlling member l9 adapted'successively to engage a plurality of contacts C duringrotary movement of the member 19 through a complete operating cycle. The timer switch Zis adapted, in conjunction with a plurality of coding circuits J and a starting circuit Reach of which is connected with one of the contacts C of the control device Z, to produce, under the. control of a keyboard K when operatingflas a, transmitter, any selected one of a number of trains of coded electrical eifectscapable of being transmitted to and made effective 'at the receivingstation to actuate operable means in response to the coded eiTects transmitted. r

The member l9,both in the transmitter and in the receiver, normally occupies a starting position in engagement with the contact C of the starting circuit F, and is connected with the transmission means T and a power source P which, inthe illustrated embodiment, comprises a direct current source, although it is obvious that other than direct-current may be employedfor the purpose of energizing the device. The cod- 7 additional combinations may be made by increasing the numberof circuits J. v 7

It will be obvious also that the circuits J may be conditioned for activity in any preferred fashion, although, as shown in the'drawings'I prefer to" c'ondition a circuit for activity by closing a switch therein or by actuating a circuit controlling element'associated therewith in response to depression of a selected key IL' The rotary contact member 9 is adapted to be driven at substantially'uniform speed by any suitable'means, such as asynchronous electric motor 2| through a clutch coupling 23 which isnoimally in uncoupled position, disabling the driving connection between the motor 2| and the member 19, which" normally occupies the starting position shown in contact with the starting circuit F.- Whi1ethe apparatus is in operation', themotor 21 is continuously turning, and the clutch means 23 is adapted'when activated, to couple the member [9 with the motor and permit the member l9 to be turned through one complete cycle of rotation from the starting position shown at the synchronous speed of the motor.

' noidSinthe starting circuit, which is controlled,

Fig. 13, by a switch 25 when the device is in condition for sending. Closure V of the switch 25, when the member 19 is in the starting position shown, energizes the starting circuit F through the power source P, actuates the clutch 23 and causes the, member H! to engage the contacts C successively during one complete revolution cycle of, the member 19, the clutch being released and the member [9 stopped in starting position at the end of the cycle, Fig. 15, r

It will be seen that, when operating as a transmitter, the timer switch, during one complete cycle, successively connects the power source and the transmission means T in series with the coding circuits J, some'or all of which areconnectet through switch means at the keyboard" K and the switch'A, with'the power source. The transmission means T consequently will be energized whenever the member l9 engages a contact C in ing circuits J andthe starting circuitF may be e trains produced passing the -same;..IEiig.. 1-5,. providine=.the corre-I sponding coding circuit is conditioned .iorcactive ityby. closure. of its; conditioning switch at the keyboard. If, f r exampl av selectedckey con:

trolling the first, 'third andjfifth codin circuits has been pressed, the, transmitter will be. enera gized when themember I Q' engagcs:thecontacts G in the first, third; and fifth circuits, asgwell. as initially by closure of the switchlli; whilemember l9 engages the contact C inthe starting circuit F. Under the conditions mentioned, however, the transmitter will noti be energized while the member t9 passes 'the contacts C in thesecnd and) fourth coding circuits, andthe' coded wave. train produced maybe represented'graphically as: XSX-X[X-O2O -X3X-.O4O- X5X; in whichXi'-.X represents-circuit activity and O.-O indicates inactivity. 1 By arranging thekeys I] to condition. different'co'mbinations:of circuits for activity, it 'will be noted that eachckey may be made to control the production of a1 characteristic coded impulse'train different from the under the control of every other key.- i V Translation system" Any preferred arrangement may be; employed for translating the codedtrains and applying the same on the receiver, and-,to thisend, I may constitute the transmitter T as a wireless radiator, or as a telegraph relay, or-otherwise-arrange thesame to activate theremote receiver-device, preferablybyjcausing closure of. a switch I lfiorming apart ofthe receiver. If desired, the transmitter T may, as shown in Figure legcornprise a relay coil, and the switch U may be located at the transmitter olirectlyunderthev influence of the coil and connected with the receiver by thetransmission linev In such anevent, the transmission line may be used in common-for two-way transmission, as indicated in dotted lines in Figure 14. I prefer, however, to locate the receiver switches, asshown in Figure '15, and to provide suitable. translation means, either wiredor wireless, for. closing the switch U at the receiving; station when the transmission means-T is energized at thesendingstations To this end, I have shown pickup or relay-meansR.

at the receiving station: adapted to be activated by the transmitter and to close the The receiver It will be seen that, when operating as a re ceiver, closure 'of the switch U, in response to the initial or starting impulse of the wave train, will complete a circuit through thepower source P and the starting circuit F, thus; energizing the solenoids andengaging the clutch 23 to drivingly connect the member H! of the timer switch Z with the driving means 21-, which is operating continuously at a speed equal to that of the corresponding means at the sending station. The member !9 at the receiving station will thus be caused to'rotate through one cycle or turn and successively to engage the co-operating contacts C in substantial synchronism with the periods of engagement of the member IS with corresponding contacts at the sending station. If during the cycle, while'the member H! at the re- 7 ceiving station is engaged with a contact C; the

switch U is caused to close, asa result of an im pulse made effective through the transmission means 2T,; the corresponding coding circuit J. at thereceiving station will be. energized-bythe power source. but; irthe switch .Urcma nsionen, While the member p se a n a t :Qat. t sending,- station, the corresponding, codingwcircuitat. the receiVingstatiQn willremaininactive.

.It will be. obviousf rom the foregoin that, during, a cycle of operation, the coding circuitsof theireceiver will be selectively energized in fashion corresponding to; that in which thecoding circuits of the transmitter are selectively energized under keyboard control. Eachof. the code ing circuits includes a solenoid H which, when its corresponding circuit is energized, operates to perform an individual control function, and while in its broadest aspect my present inven: tionis not necessarily restricted to: the particular control functions exercisedby the solenoids H, when theinvention is applied in a typewriter device as shown in the drawing, I utilize .the

solenoids H to control the selective operation of printing mechanism.

In the illustrated embodiment, the printing mechanism comprises a character wheel 13 and selector mechanism 0 co-operatively associated with the character wheel and with the solenoids H and operable to stop the character wheel in a mechanism driven by the motor 2| being provided to move the tape during the interval between the printing of successive characters,

Mechanical organization All of the operating parts of the apparatus are preferably mounted on a frame 33 which carries and embodies suitable bearings, bracketsand mountings Y. for the various elements em ploye'd. To this end, the frame 33 may comprise a relatively solidbase plate uponv which the motor 2| is securely mounted and electrically connected, as by means of a switch, with a suitable source of. energizing power. The motor is preferably arranged. at the rearv of .the device with its drive shaft projecting forwardly for connection with the operating elements of the apparatus which preferably are mounted in the forward portions of the frame'Fig. 2.

While the broaderaspects of my present invention are not necessarily limited to the particular printing mechanism illustrated, I prelfer to accomplish printing by means of a character wheel B normally maintained in continuous rotation, which wheelv may be instantly stopped in a desired angular position for the printing of a selected character and then. released, the 'wheel, to this end, operating in conjunction with selector mechanism Q under the control of. the solenoids H, and which comprises the selector wheels X, Fig. 1 1, and a plurality of stops.
